Quick Disconnect System

Periodic Reporting for period 1 - QUICK (Quick Disconnect System)

Reporting period: 2018-11-01 to 2020-04-30

The QUICK project will develop and demonstrate a novel, highly robust and reliable fault detection and mechanical isolation system to mitigate the risks of potentially highly dissipative failure modes associated with the high-performance electrical power generator technologies required for future energy-optimised aircraft.
The main objectives are:
- To define the initial requirements and a preliminary architecture of the QUICK system
- To identify and define the concept for the shaft coupling and the overall actuator, through the results of initial mechanical analyses and studies that include characterisation and considerations of available materials
- To define and develop the pre-final concept of the disconnect system, known as Version 1 prototype, including all the accessories, sensors, signal processing and data acquisition systems, all on the basis of reliability analysis
- To accurately model and simulate the behaviour of the whole set-up in order to assess all the operation effects are in play
- To define the actuation and coupling aspects of the QUICK system based on the results of a full mechanical and operational analyses
- To prototype, test and validate a full version of the whole QUICK system in a laboratory environment
- To integrate a working prototype into a realistic environment and thus be able to test and validate the concept in a realistic environment
Negotiation of the content of the project took place at the Kick-Off meeting in November 2018.
Product and system requirements were captured leading to a successful delivery of the Preliminary Architecture Definition in May 2019.
The system model was built leading to a successful delivery of Basic System Model Report in June 2019.
The Dissemination plan was delivered in June 2019.
All the requirements related to the initial design of the QUICK concept was completed which led to a successful delivery of the Preliminary Design Review (PDR) report.
The PDR review was completed with the TM in February 2020.
QUICK research results were disseminated at International conferences and Airshows
QUICK will deliver a number of ground breaking achievements that go much further beyond state-of-the-art in terms of disconnect systems.

The main attractive features include:
• A super-simple and elegant system with very low component count
• A steady state system efficiency of virtually 100%
- no electrical nor mechanical transmission of power during normal operation.
• A fully auto-synchronising system
- Coupling/decoupling is completely independent of the system speed and position.
• A very high torque transmission capability
- Magnetic couplings are known for their high torque transmission.
• All linear movement is contained within the QUICK system
• In case of any other faults within the system, it produces a natural safety slip torque.
• Very simple “control” is required
- Just a short pulse of DC current
